IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 196,304, dated October 23, 1877 application iled June 2, 1877.

- To all whom it may concern:

Be it known that l, EDMUND J.MERED1TH, of Philadelphia, Pennsylvania, have invented an Improvement in Garbureters, of which the following is a specification:

My invention consists of a vessel for containing gasoline, in combination with a series of floated or self-adjusting diaphragms constructed and arranged within said vessel, as hereinafter described, said diaphragms being re spectively provided with floats, which rest on the gasoline, and keep the diaphragms at all times in the same relative positions with re spect to the surface of the gasoline, and thus cause the air intended to be carbureted to come into contact with the gasoline, whether the carbureter is full or much depleted of the same;

ln the annexed drawings, Figure lis a plan of a carbureter embracing my improvement, the top plate being broken away 5 Fig. 2, a side elevation of the same, the side plate being removed; Fig. 3, an end view of the same, the end plate being removed 5 Fig. 4, a plan, on an enlarged scale, of one of the several similar diaphragms, with its frame and iloat.

a represents a vessel to contain gasoline. b is a partition, partially dividing the same into two compartments, c and d, which communicate at one end. e cl c2 are diaphragms, of muslin, Canton flannel, or other like spongy and pliable material, attached to frames j', which are soldered tightly to the sides of the compartment c in the inclined positions shown in Fig. 2; and c3 e4 c5 are similar diaphragms, similarly arranged, but inclined in the reverse direction inthe compartment d. g is a light plate of sheet metal on the upper, and h, Fig. 3, a frame or plate of similar metal on the under, side of the respective diaphragms, the plate and frame being held together in place by rivets, as shown in Fig. 3. Floatst are attached -to the diaphragms, respectively, by links, which allow the iioats to rest horizontally on the surface of the gasoline. The iloats e' have sufficient buoyancy to keep the mouths or outlets of the diaphragms open to the extent of about an inch or inch and a half above the surface ofthe gasoline. j are guards, to prevent the lloats from turning over on top ofthe diaphragms.

It is preferable to employ as many of the diaphragms as will work without the interference of oneuith another.

7c is the air-inlet pipe. m is ,the carburetedair-eXit pipe.

Air from a blower enters the compartment c through pipe le, passing under the diaphragms in this compartment, and thence in the direction of the arrows, under the diaphragms in compartment d, and is thus uniformly charged with gasoline-vapors, and is drawn ott' through pipe m when required for illuminating purposes.

lt will be seen that the diaphragms, being supported by the iioats, rise and fall according to the quantity of gasoline in the carbureter a. They thus operate to cause the air intended to be carbureted to come into contact with the surface of the gasoline, and produce carbureted air having uniform illuminating-power, whether the carbureter contains a full or only a scant supply of gasoline.

The carbureter is practically constructed in a variety of forms. Thus, when a small amount of carbureted air is required, the vessel a may be made without the dividingpartition, the atmospheric air being admitted at one end and drawn out carbureted at the other end; or the capacity of the carbureter may be increased by extending its length or by employing any number of carbureters, each constructed as above described, all joined together as a series, the atmospheric air being admitted at 011e end and drawn off carbureted at the other end of the series.

l claiml. A series of floated diaphragms, respectively constructed of muslin, Canton iiannel, or other like spongy and pliable material, shaped or kept inthe required form by top plates or frames g h, and attached to fixed side frames f set in inclined positions, and also iiexibly attached to a iioat, t', in combination with an inclosing-vessel, a, in the manner and for the purpose substantially as set forth.

2. The diaphragm e, constructed of muslin, Canton flannel, or other like spongy and pliable material, shaped or kept in the required form by means of top plates or frames g h., and attached to the side frames f, in combination with the iloat z', substantially as set forth.
